Dr. Aaron Chalfin received his doctorate in Public Policy from UC-Berkeley.  As an assistant professor at the University of Pennsylvania, his research interests include the costs and benefits of policing, the preferences of police officers, place-based crime prevention, and the determinants of crime victimization.

In this episode, Bad Apples, your host, Edie Driskill asks Dr. Chalfin to explain the difficulty of reducing risk profiles of police officers to simple statistics.  He helps her unpack the fallacy that many have proposed – getting rid of the few bad apples will greatly reduce the overall risk profile of policing.
